With a mid-engine car where the balance is very close to 50/50, the tire pressures would normally be about equal to create balanced handling (neither understeer or oversteer).

However, very few cars are sold with balanced handling - most cars have understeer to avoid an average driver getting into a situation that they can't control very well (oversteer).

Thus, the 29/36 recommended pressure to add a bit of understeer to the handling.
